Noctua NH-U12S Redux CPU cooler review: Noctua enters the budget market with coolers

This is the first cooler of the Redux series, to which Noctua transfers some models, making them cheaper for the mass market. It uses a familiar tower structure with 4 heat-conducting tubes, and you can get a second fan for an additional fee. Noctua has a Redux series, which eventually includes coolers and fans that seem to be no longer new, but are still in demand by the market. In fact, these are the same ordinary devices, but with a limited configuration and in a faded gray color, so if ...

Bag test of Noctua NF-F12 and NF-A14 chromax.black.swap fans

We will test with the help of a garbage bag fans that are designed to emphasize the pronounced personality of your computer, especially if it is assembled in a snow-white case. The management of Noctua constantly claims in their interviews that RGB in fans is nonsense, and it is better to spend time developing something really unique in terms of design than to succumb to the general red-blue-green madness. Of course, it sounds beautiful, but Noctua could not ignore the trends in the field of ...

Review of the 4-CPU Lenovo SR860 V2 server based on Intel Xeon Cooper Lake

A very interesting server with a price of $ 1M, created for SAP HANA and applications with high RAM consumption. Here, the processors are located one above the other, there are 3 TB of memory, 4 power supplies, monitoring with predictive analysis of breakdowns and 48 storage slots. Today we are testing a very special server from the family of vertically scalable x86 systems. The Lenovo SR860V2 quad-processor is designed to handle mission-critical workloads such as transactional and resident ...

What factors should be used to choose the server processor?

Why when choosing a processor, do not pay attention to the price per core or the price per Watt, but rather use the cost of a Megahertz with HT disabled and using Turbo Boost? Here's how it used to be good: for servers, there was a single Pentium Pro processor, which you didn't need to choose. With the advent of multi-core processors, it became clear that the more computing blocks, the better, but only until marketers stepped in and pided one CPU into ten sockets with ten cache options and ...

Review of ASRock Rack E3C242D4U2-2T motherboard for budget office server

Practically, when you need a solution for a host running a security gateway, a 1C server and a Kubernetes node, you can even give up ECC memory in favor of Core i5, Core i3 and even Pentium Gold. In general, where a high frequency is needed in single-threaded loads, it is often not enough unless a normal motherboard We love powerful 48-core processors, but not every customer is willing to pay for such capacity: even among modern companies with hybrid infrastructure (local + remote cloud), ...

Comparison of three Noctua coolers for workstations based on AMD EPYC 7000

Due to the gigantic dimensions of the socket, coolers for TR4 / SP3, as a rule, are placed in a separate category and are not compatible with anything else (this does not apply to SVO). We'll compare the top three Noctua remote cooling systems and see how they differ from each other. AMD EPYC processors have a multicrystal layout (so-called chiplets), which makes the CPU bulky in terms of size, and, apparently, the tendency to increase their CPU size will continue in the future. Since the ...

Review of ASRock Rack EP2C621D12 WS motherboard for double Xeon LGA3647 processors

Want to connect more than three GPUs with PCI-Express 16x interface? Opt for a dual-processor motherboard and go for even the simplest 6-core Xeon Bronze 3104, you have 96 PCI-E lanes. In this review, we are looking at just a budget board for Multi-GPU servers and workstations. Intel is actively promoting its LGA-3647 platform not only for the server market, but also for top-end computers designed for enthusiasts, as well as for workstations optimized for complex parallel computing. ...

Review of the server cooler Noctua NH D9DX i4 3U

This cooler is designed primarily for workstations and any installations with LGA-2011 v3 Square ILM and Narrow ILM sockets mounted in the same workspace with staff, be it storage systems or terminal servers. With its compact size, it can be absolutely silent, and if needed - for increased efficiency or maximum fault tolerance, it can be equipped with 2 fans. A good server cooler is a rarity, because the main thing for industrial PC builders is a low price, and since the noise level in ...

Review of server cooler Noctua NH-D9 DX-3647 4U for Xeon Scalable

Compact cooler for Intel Xeon Scalable series processors, compatible with both mounting types: Narrow ILM and Square ILM. It has two 92mm Pull-and-Push fans, so if you install it on a 2-CPU motherboard, you get a 4-fan tube. Initially, the Intel LGA-3647 platform was created for cloud computing, where a high density of CPU cores in one processor socket is required, but over time, quite good motherboards for workstations on Xeon Scalable appeared, and this year this processor socket looked ...
